HENRY DAVID ARMSTRONG, OF LONDON, ENGLAND.

CORKSCREW.

SPECIFICATION forming part of Letters Patent No. 747,351, dated December 22. 1903- Application led September 15, 1902. Serial No.123.4=8'7. (No model.)

To a/ZZ whom. it may concern:

Be it known that I, HENRY DAVID ARM- STRONG., a subject of the King of England, residing at 108 Maida Vale, London, England, have invented certain new and useful Improvements in Corkscrews; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in corkscrews.

The first part -of the invention refers Vto corkscrews provided with a series of levers com-- monly known as the lazy-tongs. According to my invention Iprefer to make the links forming the top parallelogram of the lazytongs longer than the other links in order to increase the mechanical advantage. In order to enable the top links to be completely collapsed, the top pivot may be made to slide in aslot cut in one of the links, or other suitable means may be provided for effecting the same object. If desired,more than one parallelogram may be formed with' links longer than the others. In order to decrease the friction, I form each pivot in one with one of the links. I further so shape the head of the screw portion that it must clear the pivot above in closing. In order to secure further mechanical advantage, I may (either in conjunction with the above improvements or otherwise) make the top of the screw portion of the corkscrew in the form of a cross-bar having, preferably, twoA slots. In each of these slots worksa pin attached to one of the levers of the lazy-tongs.

The second part of my invention refers to the collar, which embraces the neck of the bottle. With metal corkscrews as hitherto constructed this collar has been liable to break the neck of the bottle when considerable pressure has been employed. According to my invention I provide the collar of metal corkscrews with a rubber iiange or washer, against which the neck of the bottle takes as the cork is drawn. I further form' such collar with an internal rounded shoulder.

In order that my said invention may be Fig. v2 shows view of same open.

fully understood, I will now proceed to describe the same with reference to the drawings accompanying this speeification, in which- Figure 1 shows view of corkscrew collapsed. Fig. 3 shows side view of corkscrew open. Fig. 4 shows collar viewed from below. Fig. 5 shows sectional view of collar. Fig. 6 shows sectional View of rubber washer. Fig. 7 shows view of corkscrew open, the head of the screw being formed in adifferent manner from that shown at Figs. 1 to 3.

The same letters of reference denote the same parts in all the views.

a shows the links forming the top parallelogram of the lazy-tongs, such links being longer than the other links b. The top pivot c slides in a slot oZ, cut in one of the links.

e shows pivots.

f shows the collar provided, if so desired, with a rubber flange or washer, such as that shown at Fig. 6, the part ofthe washer fitting outside the 'lower part of the collar.

Zt shows internal rounded shoulder to collar f. This fits'over the mouth of the bottle.

i shows links connecting the lazy-tongs with the collar f.

j shows ythe screw. A

Referring to Fig. 2, la shows the'headof screw formed into a cross-bar, with slots Z Z, in which slide pins m m, fixed to the links b b. The slots Z Z may be inclined, if desired, instead of as shown, and the pins fm m may be fixed to other links of the lazy-tongs instead of being in the position shown. The crossbar Za is shown recessed at n to clear the pivot above when the links are collapsed.

Referring to Fig. 7, it will be seen that the cross-bar Zo is dispensed with, the head of the screw being pivoted at the lower part e, as shown.

It is understood that the number of links to the lazy-tongs may be varied. p i

What I claim as my invention, and desire to secure by Letters Patent, is-

A corkscrew comprising a series of lazytongs carrying a handle at the vupper end thereof, a bottle receiving socket carried upon the lower end of said lazy-tongs, a corksaid corkscrew-body through said socket, subscrew-body operating through said socket, a stantially as described. Io head upon said corkscrewbody disposed In testimony whereof I ax my signature transversely thereto, and provided with a in presence of two witnesses.
